E N D O G R A P H SPECIFICATION forming part of Letters Patent No. 512,025, dated January 2, 1894.

Application tiled April l5, 1893. Serial No. 470,398. (No model.)

To @ZZ whom it may concern:

Beit known that I, FRANK WOOD HAVI- LAND, of New York city, in the county and State of New York, have invented a new and Improved Endograph, of which the following is a full, clear, and exact description.

My invention relates to instruments for the vtreatment of the uterus, and especially to that class of instruments adapted to disclose the shape and dimensions of the uterine cavity, or other cavities. The instrument is arbi` trarily designated an endograph, as the object sought to be attained is to provide an instrument which will when introduced into the uterus follow the wall of the uterine cavity and likewise the wall of the cervical canal and automatically produce a diagram accurately illustrating the angles of the body cavity of the uterus, the length of the angles, the shape of said cavity, and likewise the length of the cervical canal from the mouth of external os to the internal os.

A further feature of the invention is to construct an instrument of the character above described which may be conveniently and expeditiously operated by one individual, and which will be simple in construction and capable of being readily dismantled and each part thoroughly cleaned.

The invention consists in the novel construction and combination yof the several parts, as will be hereinafter fully set forth and pointed out in the claims. Reference is to be had to theaccompanying drawings, forming a part of this specification, in which similar symbols of reference indicate corresponding parts in all the figures.

Figure 1is a plan view of the instruments applied to the uterus, illustrating the operative parts in the iirst position in positivelines and in a second position in dotted lines. Fig. 2 is a side elevation of the instru ment. Fig. 3 is a central longitudinal section, the delineating mechanism being removed. Fig. et is a transverse section on line 4-4 of Fig. l. Fig. 5 is a similar section on line 5`5 of Fig. 1. Fig. 6 is a plan'view of the tracing and delineating mechanism removed from the body of the instrument, the said mechanism being in normal and folded position, and a portion of the upper slide bar removed. Fig. 7 is a view similar to that shown in Fig. 6,

but the tracing and delineating mechanism is shown in full expanded position and both slide bars are shown in place. Fig. 8 is a side elevation of the detached delineating and tracing mechanism, a portion of the former being in vertical section. Fig. 9 is a section taken practically on the line 9 9 of Fig. 7, showing the delineating mechanism in front elevation; and Fig. 10 is a perspective lView of a shifting device employed in connection with the delineating mechanism.

The body or frame of the instrument comprises a table or base plate 10, of any approved shape; preferably,however, it is given a rectangular contour, a front and a rear cross head supported upon the end portions of the base and designated as 11 and 12, and a casing 13, of tube-like construction, which passes through and is attached i9 .each cross head, and extends a predetermined distance beyond the front head. The casing 13, is parallel with the base and is usually straight, as illustrated. Exteriorly the casing may be circular, oval, square or polygonal in cross section, but its interior is square in cross section, or practically so. The casing is provided at its rear with opposing side openings 14,1ongitudinally formed thereon and extending from a point at the rear of the forward cross head through the rear end. casing comprises two members, one over the other, and the upper member is secured to the rear cross head, but the lower member is free at its rear end, being normally supported in proper position with respect to the upper member by a latch or keeper 15, pivoted to one upright section of the rear cross head and having locking engagement with the opposing and corresponding head section, as shown in Figs. 2 and 3. The forward end or head of the casing is usually gradually reduced and rendered more or less pointed, and adjacent to the head opposing longitudinal openings 16, are made in its sides. A sleeve 17, is loosely mounted upon the forward portion of the casing, capable of being moved rearward as far as the forward cross head. The sleeve may be prevented from turning by forming a feather upon the casing, but the sleeve is held in whatever position it may be placed by a set screw 18, or its equivalent, and the set screw, when used, is provided Thus the reaigof the with a stud 19A upon its head to form a lock for forceps A, employed in connection with the instrument. The sleeve is adapted to serve as a gage, and its forward end is enlarged and provided with a guide pin 20; and if the sleeve is very long openings are made in its sides at its forward end to register with the forward casing openings 16. In order to facilitate a quick and accurate adjustment of the sleeve a scale in inches and fractions thereof may be, and preferably is, provided upon the casing adjacent to the front cross head.

The tracing mechanism B and the delineating mechanism D, are carried by a single bar 2l, which I will denominate a carriage, and both the tracing and the delineating mechanisms are operated simultaneously and in perfect unison by connected sliding bars 22 and 23, which will be hereinafter spoken of collectively as an expanding slide, since its mainfunction is to force the tracing lingers 24 and 25 in contact with opposite walls of the uterine cavityof the uterus and place the deline'ating mechanism in position to follow the movement ofthe tracing fingers; but the slide has also asecond function, that of compelling the delineating mechanism to move at all times in exact direction with the tracing fingers and produce a diagram of the cavity the tracing fingers have explored.

The body of the carriage consists of a bar provided at its rear end with a handle 27,

, preferably roughened to facilitate grasping,

anda finger guard or loop 27a at the handle end.' The tracing ingers 24 and 25, are located at the forward end of the carriage and arepivoted upon opposite faces of the carriage near opposite side edges, the pivot points being best shown in Fig. 7, and are designated as d and a. The inner ends of the fingers are wider than any other portion, and a pin 28, is located upon the inner-end of cach finger, the pins being nearly opposite the pivots yet removed some distance from them. The outerends of the fingers are made quite smooth to prevent them from unduly irritating the parts with which they are to engage. The fingers are4 furthermore preferably slightly curved and their outer ends are usually thickened upon opposite sides in order that the tingers may fold one upon the -A anism is located.

other and interlock, as shown in Figs. 6- and 8. The carriage between its center and handled end is reduced in thickness upon both faces, and at this point the delineating mechg This mechanism consists of tWO plates or bars 29 and 30, pivoted upon the opposite sides of the carriage in like manner as the tracing fingers as shown best in Fg.6, and each plate or bar is provided with an extension 3l, projecting in direction of that side edge of the carriage opposite which the particular plate or bar is pivoted, as is `best shown in Fig. 7, and each extension carries a pin 31a.

Each plate o`r bar 30 carries a socket 32 for tube constituting the socket 32, is connected with one end of a horizontal tubular arm 33, and said arm is connected with the plate or bar 30 to which it belongs by an upright postl 34, secured to the under face of the plate or bar between its pivot point and outer end, ordinarily near the rear edge, and the attachment is so made that the arm is diagonally located with respect to the plate, the outer portion diverging from the pivot of the plate. Thus when the plates arev in their `unfolded or outer position, as shown in Fig. 7, the arms will be at angles to each other. The marking material placed in the socket is maintained therein by frictional engagement with a spring-pressed plunger 35, located -in the arm 33, the spring beingl brought undervariable tension by a set screw 36. -The marking material is normally held, point below the socket, by a spring 37, passed through the rear of the arm engaged by the set screw 36, as shown in Fig. 8, one end of the spring having bearing against the under face of the arm while the other end is bowed over the top of the arm and enters a recess in the top of` the socket in order that it may press against the upper end of the marking material. See Figs. 8 and 9. When the tracing fingers are closed together the arms of the delineating mechanism occupy a corresponding position beneath the carriage, as shown in Fig. 6.

The'bars 22 and 23 of the expanding slide lie one above and the other below the carriage, and said bars'arc provided at each side of their centers with slots 38, having slide- Ways at their sides extending nearly to one end, and eachof these slots receive a stud 39, secured upon the carriage. Thel ystuds are headed and their heads have bearing upon the slides in the slots. By this means the bars of the expanding slide have movable-connection with the carriage. The upperslidc bar 22, is provided in one side edge, the righthand edge for example, with two recesses 40 and 4l, shown best in Fig. 7, adapted to snugly receive the pins carried by the right-hand tracing finger and plate of the right-hand section of the delineating mechanism. The lower slide bar 23, is provided with similar recesses in its left-hand side receiving the pins of the left-hand tracing finger and corresponding section of the delineating mechanism.

'lheslide bars 22 and 23 are each provided with a handle 42 at its rear end, extending at an angle beyond the left-hand side of the carriage, as shown in Fig. l, and the two handles are connected in any suitable manner. From the foregoing construction it will be observed that if the handle of the expanding slide is IOO IIO

` pushed forward, both the tracing fingers and delineating arms will be forced outward, or will be expanded simultaneously, and that as corresponding tracing fingers and delineating arms `have corresponding pivots, and are correspondingly connected with the expanding slide, to whatever extent or in whatever direction the fingers move the corresponding delineating arms may be moved also.

After the carriage and expanding slide have been connected they are placed in the frame inthe following manner: The latch at the rear of the frame is opened, and the arm, the tinger end of the carriage and the slide are introduced into the slotted end of the casing, the finger beingclosed, and when the fingers have reached the head of the casing the delineating arms will have passed beneath the rear cross head of the frame and will have taken a position near the forward cross head over the base. The latch is then closed, holding the carriage snugly yet capable of sliding in the casing. The casing is provided with a set screw 48, by means of which the carriage and expanding slide can be locked in the casing. In order to relieve the pivots of the delineating arms from pressure while the marker is in operation l provide a release bar 44. Shown in Fig. 10. The bar may be made of any desired material, is of greater width than thickness and has an arch 45, formed at its central portion. The bar is passed beneath the yoke section of the outer spring 37 of both arms, extending from one to the other, the arch being in engagement with the under face of the cas-v ing, as is best shown in Fig. 1. Thus no matter how much upward tension may be exerted upon the arms by the markers it will not be communicated to the pivots of the arms butwill be sustained by the release bar and casing. The release bar has another function; by turning it upon its edge the outer marker springs will be lifted from the markers and from contact with the base or whatever is placed upon the base to be drawn upon.

The forceps A used in connection with the instrument are of the self-locking pattern; their jaws 46, are hook-shaped, and when the forceps are locked extend one over the other. Back of their` pivot the members of the forceps have aligning recesses 47, produced in them to receive the stud 19 upon the set screw 18 of the guide sleeve 17.

The uterus comprises a body section E, see Fig. 1, and a neck section E'. Within the body section the uterine cavity E2, is located, whichwhen the uterus is cut longitudinally through its widest portion and is viewed from the front, as in Fig. 1, discloses the slanting side walls of the cavity, the lines diverging from the internal os, the point of which is in dicated at e. The cervical canal e', is located in the neck, and extends from the external os e2 to the internal os e.

In certain diseases of the uterus it is of great advantage to know the shape and dimensions of the uterine cavity, especially the angle of its walls and the length of the cervical canal. 'lhe instrument described is adapted for this purpose and is operated in the following manner: The uterus is first measured with a graduated sound to ascertain its length; if the length is found to be three inches, for example, the sleeve 17 is adjusted and secured upon the body casing to provide-the space of three inches between the head of the casing and the forward end of the sleeve. The tracing lingers are closed and brought close to the head of the casing, as shown in Fig. 2, which brings the delineating arms near the front cross head of the frame. Next a piece of paper` C, is placed upon the base of the frame over which the markers are to travel. The uterus is now grasped at the anterior lip 'of the canal by the jaws of the forceps, and

the head of the casing is introduced into the cervical canal at the external os; by gradually working the head of the instrumentinto the uterine cavity and drawing the neck down over the casing, the external os will be brought to the outer end of the guide sleeve, and at that time the head of the instrument will be practically in engagementwith the upper wall of the body or uterine cavity, as shown in Fig. 1. The forceps are now locked upon the instrument. Next the operator presses forward upon the handle of the expanding slide, which action throws out the tracing fingers to an engagement with opposite sides of the body cavity and the delineating arms move in the same direction. Gentle pressure is continued to be exerted upon the expanding slide to keep the tracing finger always in engagement with the walls'of the uterine cavity and cervical canal, and the carriage and slide are both gently and-slowly withdrawn from the uterus, as shown in dotted lines, Fig. 1, and as the fingers follow the outline of the uterine cavity and canal the' markers carried by the delineating arms faithfully delineate the shape of the interior of the uterus upon the paper. The forceps being locked upon the instrument the operatorhas both hands to work with and therefore may proceed with steadiness and rapidity.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An instrument of the character described comprising a carrier, an expansible and con` tractible tracer on the forward end of the carrier and contracted or folded by the walls of the cavity being traced as the instrument is being moved therealong, and a delineator l'OO IIO

ing ingers,a delineating device, and a transmitting device connecting them, whereby the movement of the fingers is precisely followed by the delineating device, as and for the purpose specified.

4. An instrument for delineating the uterine or like cavities of the body, consisting of a carriage, tracing fingers, and a delineating device connected with the carriage, and atransmitting and expanding device having movement independent of the carriage, and connecting the fingers with the delineating device, substantially as described.
